Enum CaptureState 

pub enum CaptureState {
    Captured,
    Incomplete {
        reason: String,
    },
    NotCaptured {
        reason: String,
    },
}

Whether a module’s stderr is being captured, and if not, why not.

Typed rather than nullable so NotCaptured has to be handled rather than defaulted past. An empty tail and an uncaptured one send an operator in opposite directions – one says the module printed nothing before dying, the other says nobody was listening – and rendering them alike is the defect this module exists to fix, reproduced one layer up.

Variants

Captured

A reader is attached, or was attached and reached clean EOF.

Incomplete

Retained entries are valid, but capture ended before clean EOF.

Fields

reason: String

NotCaptured

No reader was attached. The tail says nothing about what the module wrote.

Fields

reason: String
